- Settings: remove Save buttons; autosave is silent (no toast on success, error only) - Settings: loadAll() resets dirty flags to prevent stale autosave after discard - app.py: fix domain/ip_range "actually changed" check — full identity is always sent on save so these were triggering pending on every keystroke regardless - app.py: _dedup_changes handles port-change format "service field: old → new" (split on ':' not ' changed') so dns_port changed twice shows one entry - app.py: domain + cell_name changes now go through pending restart banner; apply_domain/apply_cell_name write files immediately (reload=False) and set pending; Discard restores zone files + Caddyfile to pre-change state - app.py: _set_pending_restart captures pre-change snapshot BEFORE config writes (was snapshotting after, making Discard a no-op) - app.py: is_local_request reads /proc/net/route to allow the actual Docker bridge subnet (172.0.0.0/24) which is not RFC-1918; fixes Containers page 403 - container_manager: get_container_logs raises instead of swallowing exceptions so nonexistent container returns 500+error not 200+empty Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
